Ancient Greeks personified time in the form of the titan Kronos, father of Zeus, and Egyptians celebrated Heh as an abstraction of endless years. Famously, William Shakespeare lamented humanity’s immutable fate as “time’s subjects” in Henry IV. GRAMMY® Award-nominated hard rock band Mastodon ponders the nature of time on their eighth full-length album, Emperor of Sand, on Reprise Bros. Records. Threading together the myth of a man sentenced to death in a majestically malevolent desert, the Atlanta, GA quartet—Troy Sanders (bass/vocals), Brent Hinds (guitar/vocals), Bill Kelliher (guitars) and Brann Dailor (drums/vocals), and conjure the grains of a musical and lyrical odyssey slipping quickly through a cosmic hourglass.
